Vibrating Screen

The vibrating screens are designed and tested to meet the demanding requirements of the industry with high reliability and low maintenance. These are quite effective and efficient against conventional Rotary Screens.

The main advantages are :

Long Life

Economical

Less Space

Less Maintenance

Easily Replaceable Screening Surface

Body

Body of a Vibrating Screen consists of a base frame and screen supporting structure. The base frame is welded using heavy channels and angles. Screen supporting structure and Screen are made from wear resistant Coil Steel.

Bearing

Center Shaft

Center Shaft is made of special steel and is supported at both by means of two roller bearings. Two eccentric dead weights have been provided on both ends to generate vibrations with the help of driving pulley..

Driving Motor

The foundation frame of the Driving Motor is provided by projection on one side of the Vibrating Screen and supports from base frame are also provided to hold the motor foundation. The size of motor varies as per the size of Vibrating Screen. Normally squirrel cage motor of 960 RPM is provided with the screen..

Spring

Suitable helical coiled springs are provided with the Vibrating Screen. Entire screen holding structure is supported by these springs. Special care has been taken to manufacture these springs which bear entire load along with continuous vibratory process. These springs can easily be replaced by new ones when required.

Screen

The screens are made from special coiled sheets to provide sufficient resistance to excess wear and tear. The hole size of the screening surface can be made as per the requirements of the customer. For each deck, screen surface is made from single sheet metal and stretched lengthwise to provide robust constructional service. The number of screening surface depends upon the number of decks of the screen. The inclination is given to the screen according to the suitability of work.

Driving Motor

The foundation frame of the Driving Motor is provided by projection on one side of the Vibrating Screen and supports from base frame are also provided to hold the motor foundation. The size of motor varies as per the size of Vibrating Screen. Normally squirrel cage motor of 960 RPM is provided with the screen..

Driving Pulley

This pulley is provided on one side of the center shaft with two v- grooves on it. It is directly coupled with driving motor with the help of 2 Nos. of v- belts. The dia of driving pulley has been calculated as per the requirement of No. of vibration per second.

Electronic Shaft

Dead weights with eccentricity on there center are provided on both the sides of the center which generate the vibratory action. The size of dead weight and its eccentricity vary as per the design value for each and every screen.

No. of Vibration

16 to 18 per second.

No. of Deck

Normally -2(3 or 4 deck vibrating Screens are provided against special request). in case of 3 or 4 deck Vibrating Screen one special collecting (discharge) hopper is also provided.
